Abstract

An implantable cardiac rhythm management device adapted to receive and digitize electrocardiogram signals from leads placed on or in the heart and capable of automatically adjusting an evoked response detection threshold dependent upon a modulation of the amplitude of the evoked response. Respiration, activity level, and lead maturation, among others, all effect the modulation of the evoked response and the amplitude of a signal associated with evoked response. The present invention automatically adjusts the evoked response detection threshold to account for this modulation. Without limitation, the automatic adjustment of the evoked response detection threshold may be utilized during an automatic capture verification sequence. In the event of non-capture or fusion beats during an automatic adjustment, the evoked response detection threshold is not adjusted.
